Body and facial language analysis is a most useful and under-represented/reported facet of human behavior. The show "Lie To Me" based on the work of Paul Ekman brought this topic a little bit of traction, but I've recently stumbled across a Youtube channel which very deliberately and surgically analyzes body language and facial cues in a manner that is relatively easy to interpret, learn, and develop an understanding of.
This channel does not apparently feature the orator in any way that I've seen, the videos focus solely on various subjects both mainstream and not, and desu serves as a useful resource for anons wishing to learn more about the subject.
I'm sharing it on /ub/ cuz I feel that the subject in general deserves more notice for its viability, as well as to (hopefully) provide an entertaining venue for anons to become maybe a bit more savvy.
The channel is called Bombard's Body Language: https://www.youtube.com/channel/UCXG8i4PE6-mxh52nFKwMkcg/featured
This thread is therefore geared toward the discussion of body and facial language interpretation, encouraging a sharing of resources to develop an individual's ability to perceive beyond simply 'what people say'.
